I repeatedly attempt the same task. My probability of success, on the kth attempt is p ∈ (0, 1), irrespective of the outcomes of all previous attempts. What is the probability that my first success occurs on an odd numbered attempt (the first attempt is numbered 1).
I repeatedly attempt the same task. My probability of success, on the kth attempt is k(k + 2)/(k + 1)2, irrespective of the outcomes of all previous attempts. Here k ∈ {1, 2, 3, . . .} What is the probability that I never fail?

Negative Binomial experiment is based on sequences of Bernoulli trials with probability of success p. Let x+m be the number of trials to achieve m successes, and then x has a negative binomial distribution. In summary, negative binomial distribution has the following properties Each trial can result in just two possible outcomes. One is called a success and the other is called a failure. The trials are independent The probability of success, denoted by p, is the...

In assessing the effecitveness of a new treatment: 70% of all participants entering the study will never successfully get positive results. Among the remaining individuals who could potentially get positive results: there is a 50% probability of success on any given attempt, independent of the results of any previous attempts. What fraction of all participants in the study will success on the first attempt? What fraction of participants who fail to success on the first attempt and who make a...

A discrete probability distribution differs from a continuous probability distribution, by only taking values on a discrete set (like the whole numbers) instead of a continuous set. The geometric distribution is a discrete probability distribution which measures the number of times an experiment must be repeated before a success occurs. For example, in this problem, we will roll a fair six-sided die until the number six occurs, at which point we stop rolling. (a) If we are rolling a die,...

Four people working independently on an assembly line all perform the same task. The time (in minutes) to complete this task for person i, for i=1,2,3,4, has a uniform distribution on the interval [0, i]. Suppose each person begins the task at the same time. a) What is the probability that person 2 takes less than 90 seconds to complete the task? b) What is the average completion time for each person? c) What is the probability that all four...

I am playing a simplified version of the card game, "War," with my brother. We are playing with a subset of the deck, all of the numbered cards 2 through 10 (2:10). There are 4 cards of each number, resulting in 36 total cards in a single pile. First, I turn over a card. Next, he turns over a card. Whoever has the higher card wins and these "used" cards are discarded. If we turn over the same card, we...

2. In my youth, I had friends who played AD&D. If my character is attacked, there is a 25% chance the attack will be successful (and damage from that attack is determined by rolling a fair 10-sided die with the resulting value subtracted from the character's current hit points) You should be familiar with dice, but just in case: the values on the dice are numbered sequen- tially starting at 1 a. With a fair 8-sided die, what values would...
